A trio of actors have signed on for the psychological voodoo-themed thriller Vipka. Variety reports that Forest Whitaker, Anthony Mackie and Sanaa Lathan (AVP: Alien vs. Predator) are set to star in the genre flick. Philippe Caland (Ripple Effect) is directing, and the story “follows two adversaries who go head-to-head in a game that will test each man’s belief in what they’re certain is the truth.” While the logline’s a bit vague, we know voodoo’s in there somewhere, so expect Whitaker and Mackie to go all crazy.
